IMPROVEMENT lN WATER-CLOSETS.

Specification forming part of Letters Patent No. 187.089, dated February6, 1877; application filed August '25, 1876.

. State of Michigan, have invented an Improved Water-Closet, of whichthe following is a specification:

The object I have in view is to construct a Water-closet adapted toreceive the common or trade bowl, that will be cheaper to make, morecertain in operation, and easier to repair than closets heretofore used.

The invention consists, first, in the peculiar conformation of the trunkand its flanges, one of which is adapted to receive an annular rubbervalve-seat, and be secured thereon by a removable ring-plate, access towhich is had by simply removing the bowl; secondly, the combination,with said seat, of an upwardlyclosing valve, mounted on a swinging armat the end of a rock-shaft actuated by the closetpull; thirdly, inextending upwardly the mouth of the trunk to receive the mouth or neckof the bowl, thus forming a trap-chamber above the valve, which issealed by water to exclude the sewer-gases; fourthly, in combinationwith said trap-chamber, an overflow cast or formed in the trunk,extending from a point under the bowl-flange to a point below the valve,to carry oil the surplus of flushing-water or any leakage from thewater-valve, and in the arrangement of the various parts, as more fullyhereinafter set forth.

Figure 1 is a perspective view of the closet and bowl. Fig. 2 is avertical section of the same. showing the cl0set-valve closed. Fig. 3 isa similar section, showing the closet-valve opened. Fig. 4 is a bottomperspective view of the closet-valve and arm. Fig. 5 is a crosssectionof said valve at a; w.

In the drawing, A represents the body of the trunk, with a flaring upperpart, A having an internal flange, a, near the top, for the flange b ofthe ordinary trade-bowl B to rest upon, whereby the latter is supportedin position. Access is had to the interior of the lower part of thetrunk through a square flanged opening, A on one side, which opening isclosed by a suitable cover. The part A is cast with an internal flange,c, at its top, on which is laid a flat rubber ring, d, of the samediameter over all, but whose central opening is less in diameter thanthat of said flange c. The ring d serves as a valve-seat, and is held inplace by a fiat metal ring, 6, of the same diameter, laid thereon, andsecured by two screw-bolts,f, tapped through into the flange c. Theentire trunk A A A and its flanges is molded in one piece, whether inmetal or earthen ware, and at the same time I prefer to cast in anoverflow-passage, g, extending from a point just under the flange a to apoint below the flange c.

The neck h of the bowl extends down nearly to the ring 6, so that whenthe opening in the valve-seat is closed the sealing-water flowing downthe bowl will fill the chamber above the valve to a level with the topof the overflowpassage g, thereby forming a trap to exclude gases risingfrom the soil-pipe, independent of the trap in the latter.

0 is a rock shaft, journaled in bearings halved in the upper part of thetrunk-flange A and its cover, and is provided with an arm, D, having aslot, 2', longitudinally cut therein. E is the pull-up lever, pivoted ona stud at the side of the trunk, its long arm being weighted to keep itdown.- The short arm, when depressed, actuates the water-valve (notshown) in the usual manner, while a pin, working in the slot 2' of thearm D, actuates the rock-shaft, on which there is secured an arm, F, towhich a brass disk-valve, G, is pivoted by a pin, k, as seen in Fig. 4,and in such a manner that it has aslight oscillation, so as to adjustitself to thevalve-seat, which is an essential feature, as it avoids theexpense of making an accurate fit in the first instance; andsubsequently, if the seat wears or compresses unequally, it will (thevalve) accommodate itself thereto.

When the seat requires renewal, all that is necessary to do is to liftoff the bowl, remove the bolts f, and lift off the ring 0, when the newseat-ring may be put in and secured, as hereinbefore described.

I am aware of' the patent granted April 7, 1868, to William S. Carr, anddisclaim the devices shown and described therein as making any part ofmy invention; but

What I claim as my invention is-- 1. The trunk A A A provided with theoverflow g, the flange a to support the bowl B, and the flange c tosupport an annular elastic valve-seat, in combination with an up- 3. Theelastic annular valve-seat 01, secured wardlyclosing valve,substantially as deto the flange c of the trunk by the ring 6 andscribed. bolts ff, substantially as described.

2. In a watercloset, the combination, with 4. The valve Gr, looselypivoted to the arm the trunk A A A and upwardly-closing valve F of therock-shaft G, the same being actuated G, of the bowl B, extending downinto the by the lever E substantially as described.
